Hi, folks. I've just noticed that grubby 8.35-6.fc21 made it to the updates-testing repository. That build has a rather bad bug - when it writes grub entries it will likely leave out the 'initrd16' (or just 'initrd', depending how old your system is) line, which will probably mean the kernel won't boot. So, best downgrade to 8.35-4.fc21 (from the 'fedora' repo) or upgrade to 8.35-7.fc21 (https://admin.fedoraproject.org/updates/FEDORA-2014-12932/grubby-8.35-7.fc21 , should hit updates-testing soon, you can get it from koji or with 'bodhi -D FEDORA-2014-12932' for now) before installing any kernels. If you do wind up with a grubby 8.35-6 installed kernel which won't boot, don't panic. You can manually add the required line by copying from the line for an older kernel and just changing the filename appropriately - it should come right under the 'linux' / 'linux16' line. You can also just boot an older kernel, remove the newer kernel, upgrade or downgrade grubby, and install the newer kernel again.
